Bottling machines

ABSTRACT

A bottling machine for filling bottles with a liquid under the action of pressure gas includes a single reservoir (1) for the liquid and pressure air, such reservoir being provided with a float (2) serving to prevent contact of the pressure air with the liquid and to prevent the formation of waves on the liquid surface when the machine is started or stopped. The float may take various forms, for example it may be formed as a hollow body (3) of revolution made of non-oxidizable material, as a solid body (5) of revolution made from a material having a specific gravity of less than one, or as a buoyant open section (7) made of non-oxidizable steel. In another form of the invention, the float is formed from a plurality of interconnected sections (8).

In such machines, an important problem is to avoid the dissolving of oxygen in the liquid being transferred.

In bottling machines employing a single reservoir for the liquid and pressure air, the presence of the air can result in the following drawbacks:

a. a large surface of contact between the liquid and the air b. agitation of the liquid surface occurring when the machine is started or stopped.

It is an object of the present invention to obviate these drawbacks, and accordingly the invention provides a bottling machine having a single reservoir for the liquid and pressure air, in which machine there is provided in the reservoir a float which serves to prevent contact between the liquid and the pressure air and to prevent the formation of waves on the liquid surface when the machine is started or stopped.

Other objects and advantages of the present invention will be apparent from the following detailed description of certain preferred embodiments thereof, as shown in the attached drawings, in which FIG. 1 illustrates an annular reservoir of a bottling machine embodying the invention, showing a float positioned within the reservoir FIGS. 2, 2A and 2B illustrate various forms of hollow float FIGS. 3, 3A and 3B illustrate various solid floats which may be used FIG. 4 illustrates a float in the form of an open channel and FIG. 5 illustrates a float constructed from a plurality of sections.

Referring to FIG. 1, an annular reservoir I of a bottling machineis provided with a float 2 adapted to prevent contact between liquid and pressure air within the reservoir and to prevent the formation of waves on the liquid surface when the machine is started or stopped.

In addition, the float may serve as a control element for regulating the liquid level or gas pressure in the reservoir.

The float may take any of the following forms A. A hollow body 3 made of non-oxidizable material and generated by the rotation of any suitable surface about an axis 4 (FIGS. 2, 2A and 28).

B. A solid body 5 made of a material of specific gravity less than I and generated by the rotation of any suitable surface about an axis 6 (FIGS. 3, 3A and 33).

C. An open section 7 made of non-oxidizable steel and buoyed up by air or gas (FIG. 4).

As shown in FIG. 5, the float may be formed from a number of sections 8 connected together by a flexible band 9 to which are secured elements 10 and 11 for forming the portions 8.

WHAT I CLAIM IS 1. A reservoir for a bottling machine of the kind used to transfer liquid into bottles under the action of air pressure comprising a single annular reservoir for both the liquid and the air under pressure, the said reservoir having a float disposed therein to prevent the absorption of oxygen into the liquid and to prevent the formation of waves when the machine is started or stopped.

2. A bottling machine according to claim ll, wherein the float is constructed from a non-oxidizable material in the form of a hollow body of revolution generated by the rotation of any suitable surface about an axis of revolution.

3. A bottling machine according to claim 1, wherein the float is constructed from a material having a specific gravity less than one in the form of a solid body of revolution generated by the rotation of any suitable surface about an axis of revolution.

4. A reservoir according to claim 1, wherein the float is constructed from a non-oxidizable steel in the form of an open section enclosing air or gas.

5. A reservoir according to claim 1 wherein the float comprising a plurality of interconnected sections.

6. A reservoir according to claim 5 wherein the sections are interconnected by a flexible band to which are connected elements for forming the portions.
